Watch out for espares. I ordered a replacement handle from them for my freezer, and quoted part numbers and all, but the thing they sent was utterly different, not a handle at all. And getting the refund was a nightmare.
Many manufacturers are not interested in the sale of spares to the public, who are likely to only want one part.
Best to do a web search for your required part.
I have used the outfit Ecclescake suggests (for oven parts), I can report that delivery is quick – and they were the cheapest I found (but not as cheap as I’d like) – but that’s the nature of the spares business.
